In the automotive industry, precision is everything. Countless components operate within hydraulic systems, oil circuits, and delicate mechanisms where even the tiniest foreign particle can cause serious problems. Yet one quality factor that manufacturers often overlook — despite its significant impact — is particle cleanliness.
Microscopic metal shavings, plastic fragments, or tiny fibers invisible to the naked eye can silently compromise the performance and lifespan of critical components. That’s why particle analysis is no longer just an inspection task — it’s a core pillar of any robust quality management system.
The Standards Behind the Science: VDA 19 & ISO 16232
Two internationally recognized standards govern particle cleanliness testing in the automotive world:
Table
Standard
Role
VDA 19
Provides procedural guidelines and test methods
ISO 16232
Establishes universal criteria for communication between OEMs and suppliers
Using both standards together ensures that particle analysis results are globally comparable, traceable, and credible — making it easier for factories to benchmark quality and meet OEM expectations.
Why Does It Matter?
Even particles just a few microns in size can trigger unexpected failures, such as:
Blocked oil channels in hydraulic systems
Increased friction and wear in precision moving parts
Stiffening of mechanical components, reducing responsiveness
False signals in electronic systems, causing malfunctions
Think of particle analysis as a preventive health check for your production line — identifying contamination risks before they turn into real-world failures.
How Particle Analysis Works: A 2-Step Process
Step 1: Decline Test — Validating Extraction Parameters
The first step under VDA 19 is the Decline Test, which verifies that the particle extraction method is appropriate for the specific component being tested. This confirms that all potentially contaminating particles are consistently extracted — with no variability caused by equipment or methodology.
⚠️ If the Decline Test fails, it signals instability in the production or cleaning process — which must be corrected before proceeding to the main analysis.
Step 2: Particle Analysis — Classification and Quantification
Once extraction is validated, particles are categorized into three groups:
Metallic — metal shavings or fragments from machining
Non-Metallic — plastic, rubber, or other solid particles
Fiber — thread-like contaminants from packaging or assembly
This classification tells manufacturers not just how many particles are present, but what type, what size, and — critically — where they came from: machining, assembly, surface finishing, or even component packaging.
4 Real Business Benefits of World-Class Particle Testing
1. ⬇️ Reduce Scrap and Production Costs
Once the source of contamination is pinpointed, targeted corrective actions — such as improving washing steps or adding dust protection — lead directly to lower scrap rates and more stable production output.
2. Boost Supplier Credibility with OEMs
Reporting to ISO 16232 means your results speak a universal language that OEMs understand and trust — eliminating interpretation gaps and positioning your factory as a reliable, quality-controlled supplier.
3. Enable Continuous Process Monitoring
Particle data allows factories to track cleanliness trends over time, enabling proactive maintenance planning and preventing quality issues from ever reaching the customer.

n today’s world, where product quality control and safety are non-negotiable for any business, GC-MS (Gas Chromatography-Mass Spectrometry) has emerged as one of the most powerful analytical tools available — giving businesses the confidence that their products are truly safe and up to standard.
In this article, we’ll break down what GC-MS is, why it matters across industries (especially food), and how ALS Testing Services (Thailand) can support your business with world-class testing expertise.
What Is GC-MS? A 4-Step Process Explained
GC-MS is an advanced chemical analysis technique that combines two powerful instruments:
GC (Gas Chromatography) — separates the individual compounds within a sample
MS (Mass Spectrometry) — identifies and measures each compound by analyzing its mass and chemical structure
Together, they allow scientists to identify and quantify substances in a sample with exceptional precision, speed, and detail.
Here’s how the process works, step by step:
Step 1: Sample Injection
The sample — prepared as a liquid or gas — is precisely injected into the GC instrument via an automated injector. A carrier gas then transports it into the separation column. Temperature and pressure are carefully controlled at this stage to preserve sample integrity and ensure accurate results.
Step 2: Compound Separation
Inside the GC column — a long, ultra-thin tube coated with a special material — individual compounds travel at different speeds depending on their chemical affinity to the coating and their boiling points. This causes each compound to exit the column at a different time, effectively separating the mixture into its individual components, one by one.
Step 3: ⚡ Compound Detection
Once separated, each compound enters the mass spectrometer, where its molecules are converted into ions through ionization (using electrical energy or light). The MS then measures each ion’s mass-to-charge ratio (m/z) — essentially a unique “fingerprint” for each substance.
Step 4: Data Analysis and Identification
The MS output is converted into a mass spectrum graph, which displays the distribution and intensity of ions. Analytical software then compares this spectrum against a large reference database of known chemical signatures to identify exactly what substances are present — and in what quantities. This data forms the foundation for evaluating product safety and quality.
Why GC-MS Matters: Key Benefits for Your Business
GC-MS plays a critical role across multiple industries — food & beverage, pharmaceuticals, environmental science, and chemicals. Here’s why it’s indispensable:
Highly Detailed Chemical and Contaminant Analysis
GC-MS can detect a wide range of complex organic compounds at extremely low concentration levels — from pesticide residues in food, to environmental toxins, to contaminants in medical products.
✅ Ensuring Product Quality and Safety
For businesses producing products that demand high safety standards — food, cosmetics, pharmaceuticals, or medical devices — GC-MS testing confirms that products are free from harmful substances, giving both you and your customers peace of mind.
Supporting Regulatory Compliance
Many countries and industries require strict testing for chemical residues and contaminants. GC-MS is the go-to tool for meeting these requirements, helping businesses avoid fines, product recalls, and regulatory penalties.

As the automotive industry shifts into the electric vehicle (EV) age, countless components are being redesigned to be lighter, more energy-efficient, and capable of handling high-voltage electrical systems. Modern EVs are no longer built from steel alone — they incorporate aluminum alloys, mixed metals, plastics, and extensive electronics, all working together in increasingly complex structures.
But that complexity comes with a hidden risk: corrosion.
The Corrosion Challenge in Electric Vehicles
The multi-material construction of EVs creates several corrosion vulnerabilities, including:
Localized (pitting) corrosion on aluminum and alloy components
⚡ Galvanic corrosion at joints where dissimilar metals meet
Degradation of electrical connectors and busbars from salt mist and moisture
These risks are especially significant in high-humidity coastal areas, or heavily polluted urban environments, where corrosion can accelerate far faster than engineers anticipate — putting long-term user safety at risk.
The most vulnerable areas in an EV include:
Underbody structural panels
Battery packs and mounting brackets
Electrical connectors and wiring trays
Battery cooling pipes and heat dissipation plates
For both parts suppliers and original equipment manufacturers (OEMs), managing corrosion is not just about aesthetics — it directly affects safety, reliability, and long-term costs. This is where the Salt Spray Test becomes essential.
What Can a Salt Spray Test Tell You About EV Components?
The Salt Spray Test (also known as a Salt Fog Test) simulates a harsh environment of continuous salt mist and high humidity to assess how well a component resists corrosion. Here’s what it can reveal:
1. When Corrosion First Appears
One of the key metrics is recording exactly when rust or surface changes begin after the test starts. This data can be benchmarked against OEM specifications to determine pass or fail.
2. The Pattern of Corrosion
The test doesn’t just tell you whether corrosion occurs — it shows how it occurs. Engineers can identify:
Pitting on aluminum surfaces
Coating delamination (peeling protective layers)
Corrosion at dissimilar-metal junctions
These insights help manufacturers pinpoint whether the root cause lies in the component design, surface preparation, or the coating process itself.
3. ️ Coating System Effectiveness
For coated or painted components — such as battery brackets, underbody panels, or electric motor housings — the test verifies whether the protective coating actually works. Early peeling or rust signals a weakness in the coating formula or process that needs to be addressed.
Why Salt Spray Testing Is Critical to OEM Standards
The increased complexity and safety risks of EV structures have made corrosion testing a mandatory quality gate for OEM approval. Here’s why:
1. Reducing High-Voltage Electrical Safety Risks
Electrical connectors, busbars, and battery components are highly susceptible to oxide film formation and surface corrosion. Keeping these free from salt-induced corrosion helps prevent short circuits and abnormal heat buildup in the electrical system.
2. Ensuring Structural Reliability
Underbody frames, battery mounting assemblies, and load-bearing structures that rust prematurely can lose structural strength — with serious safety implications. Passing the Salt Spray Test to OEM standards confirms that components can withstand real-world conditions.
3. Meeting International Standards and Enabling Traceability
Global OEMs reference standards such as ASTM B117 and ISO 9227, alongside their own internal specifications. Certified lab results are critical for part approval before production begins at an industrial scale.
The data from Salt Spray Testing is not just a pass/fail verdict — it is a strategic tool that gives engineering and quality teams a clear direction for continuous improvement.
Test Your EV Components with ALS Testing
For manufacturers aiming to become suppliers to EV-era OEMs, taking Salt Spray Test data seriously can meaningfully reduce scrap rates, minimize warranty claims, and open doors to long-term business opportunities.

ESG Is No Longer Just a Trend — It Is a Business Imperative
Environmental, Social, and Governance (ESG) reporting has moved from a voluntary best practice to a core business requirement. Investors, regulators, customers, and the public now expect organizations to back their sustainability claims with data that can actually be verified.
For industrial organizations, one of the most critical — and often underestimated — environmental indicators is Volatile Organic Compounds (VOCs). These invisible chemical compounds touch all three pillars of ESG, making accurate VOCs analysis far more than a technical exercise.
What Are VOCs — and Why Do They Matter for ESG?
Volatile Organic Compounds (VOCs) are chemicals that evaporate easily at room temperature. They are released during manufacturing processes, fuel combustion, and a wide range of industrial activities — often without being seen or smelled until concentrations reach harmful levels.
Their relevance to ESG spans all three dimensions:
Table
ESG Pillar
How VOCs Connect
Environment
VOCs monitoring reflects how effectively an organization controls its air emissions and environmental impact
Social
Exposure to VOCs directly affects worker health and safety — a core social responsibility
Governance
Accurate, traceable VOCs reporting demonstrates organizational transparency and accountability
VOCs data is not just a technical concentration value. It is evidence of how seriously an organization takes its responsibility to people and the planet.
Accuracy Is Everything — Here Is Why
Getting VOCs analysis right requires two things working together: proper sample collection and laboratory-grade analysis.
Portable field instruments like PID detectors are useful for quick, on-site readings — but they cannot identify specific compounds or produce the defensible results required for formal ESG reporting.
For that, laboratory analysis is essential. The most widely used technologies include:
GC-MS (Gas Chromatography–Mass Spectrometry) — the gold standard for identifying and quantifying individual VOC compounds with precision
HSGC (Headspace Gas Chromatography) — optimized for analyzing VOCs in water samples
SPE (Solid Phase Extraction) — used to prepare soil and water samples before GC-MS analysis
But technology alone is not enough. The accuracy of results also depends on:
How samples are collected and preserved
The chain of custody maintained during transport
The laboratory’s internal quality control systems
Weak processes at any of these stages can produce misleading data — and in an ESG context, misleading data carries real consequences.
VOCs Across Three Environmental Media
VOCs do not stay in one place. They migrate through air, water, and soil — which means effective monitoring requires a tailored approach for each medium.
️ Air
Air samples are collected using sorbent tubes or continuous sampling methods, then analyzed by GC-MS to identify specific compounds and concentrations. VOCs air monitoring is essential for:
Controlling workplace air quality
Assessing emission levels in and around industrial facilities
Meeting occupational health and environmental regulations
Water
Because VOCs evaporate rapidly, water sampling demands airtight containers and careful handling to prevent loss before analysis. Using HSGC combined with GC-MS delivers precise results critical for:
Evaluating water quality near industrial sites
Assessing safety for consumption or discharge
Supporting environmental impact assessments
Soil
In areas with a history of industrial activity, multi-point soil sampling ensures comprehensive coverage. Samples undergo SPE preparation before GC-MS analysis, providing data essential for:
Long-term environmental risk assessment
Contamination source identification
Regulatory compliance and site remediation planning
The Laboratory’s Role in Building ESG Credibility
In the ESG framework — particularly under Environment and Governance — environmental data must be both accurate and traceable. This is where the laboratory becomes a strategic partner, not just a service provider.
A credible accredited laboratory delivers:
✅ Rigorous quality control at every stage of analysis ✅ Calibrated instruments maintained to international standards ✅ Systematic documentation that creates a clear audit trail ✅ Results that hold up — whether submitted to regulators, included in ESG reports, or shared with investors and partners
When VOCs data comes from a reliable, accredited source, it transforms from raw numbers into verifiable proof of environmental stewardship.
Data That Means Something
In the age of ESG, the numbers in your sustainability report are scrutinized more carefully than ever. They need to be:
Accurate — reflecting what is actually happening in your operations
Traceable — supported by documented methodology and chain of custody
Credible — produced by laboratories recognized locally and internationally
A concentration value is just a number. Verifiable, well-documented VOCs data is evidence — of accountability, of transparency, and of a genuine commitment to sustainability.
Organizations that invest in rigorous VOCs analysis are not just checking a compliance box. They are building the data foundation that ESG credibility requires.

Why Chemical Testing Is the Foundation of Credible ESG Reporting
Numbers Only Matter If They Are Right
Every organization calculating its Carbon Footprint is working toward the same goal: an accurate, credible, and defensible picture of its greenhouse gas emissions. But here is the question most overlook —
How reliable is the data behind those numbers?
Carbon Footprint reporting, as defined by frameworks like the GHG Protocol and ISO 14064, is fundamentally a calculation. It takes Activity Data — fuel consumed, waste generated, refrigerants used — and multiplies it by established Emission Factors to estimate total greenhouse gas output.
The formula is standardized. The methodology is clear. But if the input data is inaccurate, even a perfectly executed calculation produces a misleading result.
This is exactly where chemical testing becomes essential.
What Is Chemical Testing — and What Does It Have to Do with Carbon?
Chemical testing is the process of collecting and analyzing samples from environmental media — air, water, soil, waste streams, and process gases — using standardized methods and equipment. The goal is to determine concentration, composition, and potential impact on the environment, human health, or regulatory compliance.
In the context of Carbon Footprint reporting, chemical testing is not about measuring carbon directly in a lab. Rather, it is about validating the quality of Activity Data — ensuring that what goes into the calculation actually reflects what is happening on the ground.
Carbon Footprint is the calculation. Chemical testing is what makes the inputs worth calculating.
Where Chemical Testing Makes a Real Difference
In complex industrial operations, relying on generic averages or assumptions introduces significant margin for error. Chemical analysis replaces those assumptions with real, site-specific data:
Table
Application
How It Improves Accuracy
Fuel Heating Value Analysis
Uses actual calorific value instead of generic averages
Stack Gas Measurement (CO₂, CH₄, N₂O)
Directly assesses combustion efficiency and emission rates
Wastewater COD Analysis
Calculates methane generation potential from treatment systems
❄️ Refrigerant Identification (HFCs, PFCs)
Ensures the correct Global Warming Potential (GWP) value is applied
Raw Material Composition Analysis
Supports accurate Scope 3 emission assessments
In each of these cases, chemical testing acts as a data verification layer — not replacing the Carbon Footprint calculation, but making the data that feeds it far more trustworthy.
Why Data Integrity Is Non-Negotiable
A Carbon Footprint report that earns stakeholder trust is not just mathematically correct — it is traceable, transparent, and verifiable. The factors that determine credibility go beyond the calculation itself:
✅ How Activity Data was collected and recorded
✅ Whether international standards are clearly referenced
✅ Internal quality control systems in place
✅ Transparency throughout the reporting process
Within the broader ESG framework — particularly on the environmental and governance dimensions — verifiable data is the bedrock of long-term credibility. Investors, regulators, customers, and partners are increasingly asking not just “What is your carbon footprint?” but “How do you know?”
More Than a Statistic — A Reflection of Who You Are
The figures in a Carbon Footprint report represent far more than emissions data. They are a statement of organizational accountability and transparency.
Choosing to ground your reporting in accurate, chemically verified data does two things at once:
Reduces the risk of reporting errors that could damage credibility or invite regulatory scrutiny
Builds a stronger foundation for long-term sustainability — one that holds up under audit, due diligence, and public disclosure
In an era where ESG performance is increasingly tied to business reputation and investment attractiveness, the quality of your data is the quality of your commitment.
The carbon numbers you report are only as strong as the data behind them. Make sure yours are built to last.

The Invisible Threat in Every Factory
Dust.
Fumes.
Chemical vapors.
They are present in nearly every manufacturing environment — and most of the time, you cannot see them.
As air pollution and industrial health concerns grow globally, workplace safety is no longer just a regulatory checkbox. Employees, business owners, and the public are paying closer attention to what workers breathe every day. Regulations are tightening. Standards are rising. And for good reason.
In many production processes, the real danger is not the accident you can see — it is the hazard you cannot.
Vapors released from solvents, paints, and adhesives
Fine dust and particles generated from grinding, cutting, or friction
Invisible residues and contaminants that accumulate on work surfaces over time
None of these cause immediate, dramatic symptoms. But prolonged exposure quietly damages the respiratory system, the nervous system, and overall health — often before anyone realizes there is a problem.
Factories that want to grow sustainably need tools that make these invisible risks visible. That is exactly what VOCs testing and FT-IR analysis are designed to do.
Two Tests, One Powerful Combination
VOCs Testing — What Is in the Air?
VOCs (Volatile Organic Compounds) testing measures the concentration of airborne organic chemicals in the workplace — production floors, enclosed processing areas, and anywhere chemical use is involved.
The results give factories clear, actionable intelligence:
Which areas carry the highest inhalation risk
When contamination levels spike above safe thresholds
Where to improve ventilation or adjust processes
Perhaps most importantly, having real numbers eliminates uncertainty. When employees ask “Is the air here safe?”, management can answer with data — not reassurances.
FT-IR Analysis — What Is That Dust?
FT-IR (Fourier Transform Infrared Spectroscopy) takes a different but equally important angle. Rather than measuring air quality, it identifies the chemical identity of solid particles, residues, and contamination found in the workplace.
FT-IR works by analyzing how a material absorbs infrared light — producing a unique chemical “fingerprint” for each substance. Even from a tiny sample, or from dust invisible to the naked eye, FT-IR can accurately identify:
Plastics, rubber, and resins
Fibers and polymer materials
Chemical residues and unknown contaminants
Knowing exactly what the dust is allows factories to:
Pinpoint the true source of contamination
Adjust production processes or switch to safer materials
Reduce product defects and production waste
Better Together
VOCs and FT-IR are highly effective individually — but together, they provide a complete picture.

Key Benefit
Health risk assessment
Root cause identification
When used in combination, factories gain insight into both the air their people breathe and the materials their processes produce — enabling smarter, more targeted improvements across health, safety, and production quality.
Long-Term Benefits That Go Beyond Compliance
Better Production Quality
When you know exactly where contamination comes from, you can control it. Fewer defects. More consistent output. Greater confidence from customers and partners.
Lower Operating Costs
Solving problems with precise data eliminates costly guesswork — less rework, fewer unplanned line stoppages, and less wasted raw material.
A Workforce That Trusts You
When employees see that air quality and contamination are being actively monitored, they feel valued — not overlooked. That trust translates into stronger engagement, fewer grievances, and lower turnover over time.
Audit-Ready, Every Day
VOCs and FT-IR results serve as verifiable, scientific documentation of systematic risk management — whether facing regulatory inspections, occupational health audits, or assessments from business partners and clients.
From Invisible Risk to Informed Action — with ALS Testing
Creating a truly safe workplace is not a one-time exercise. It is an ongoing commitment built on reliable data.
By combining VOCs and FT-IR testing, factories can transform hidden risks into actionable insights — enabling precise adjustments to ventilation systems, material choices, and work procedures that protect both people and processes.
ALS Testing — a globally accredited laboratory operating in Thailand — brings world-class VOCs and FT-IR testing to your doorstep. No overseas sample submissions. No complicated logistics. Just internationally standardized results that give your factory the clarity it needs to keep improving.
Because workplace safety should not be a policy on paper. It should be part of how your business grows.

The Real Cost of Wrong Materials
In industrial and construction projects, quality failures rarely announce themselves immediately. By the time a problem surfaces — a coating that peels, a sealant that cracks, a polymer that fails under load — the damage is already done, and the cost to fix it is exponentially higher than it would have been to prevent it.
The most effective quality strategy is not inspection after the fact. It is verification at the source.
That is precisely where FT-IR (Fourier Transform Infrared Spectroscopy) plays a decisive role — as a powerful, science-backed first line of quality control.
What FT-IR Actually Does
FT-IR is an analytical technique that identifies the chemical structure of a material by measuring how it absorbs infrared light. Each material produces a unique spectral “fingerprint,” revealing:
What the material truly is — not just what it appears to be
What chemical groups it contains
Whether any chemical changes have occurred
It does not measure structural strength or load-bearing capacity. What it does — with speed and precision — is confirm that the material in your hands is exactly what it is supposed to be.
10 Ways FT-IR Strengthens First-Line QC
1. Confirm Material Identity Before Use
Is this epoxy, polyurethane, silicone, or something else entirely? FT-IR answers that question with certainty — preventing the wrong material from ever entering your process.
2. Filter Materials Before Expensive Testing
Mechanical and safety testing is time-consuming and costly. FT-IR acts as the first gate, ensuring only chemically verified materials move forward — saving both time and resources.
3. Track Quality Consistency Across Production Lots
The same product from different production batches is not always the same. FT-IR detects batch-to-batch variation, keeping quality consistent from project start to finish.
4. ⚠️ Detect Formula Changes or Unauthorized Substitutions
If a supplier changes raw materials, reduces key components, or delivers an off-spec formulation, FT-IR will reveal the chemical difference — clearly and objectively.
5. ️ Assess Material Condition, Not Just Type
FT-IR goes beyond identification. It can detect signs of thermal degradation, UV damage, or oxidation — providing early warning signals before a material fails in the field.
6. ️ Replace Guesswork with Science
Many materials look identical to the naked eye. FT-IR eliminates reliance on visual inspection or experience alone, replacing assumptions with hard analytical evidence.
7. Reduce the Long-Term Cost of Failure
Catching the wrong or degraded material at incoming inspection costs a fraction of what field failures, rework, or post-installation damage will demand. Prevention always pays.
8. Build a Traceable Quality Record
FT-IR results are documented, verifiable, and traceable — serving as reliable technical evidence in quality disputes and informed decision-making for engineers and management alike.
9. ⚡ Fast, Non-Destructive, and Non-Disruptive
Testing is rapid, requires minimal sample material, and does not interrupt production lines — making it perfectly suited for incoming inspection and routine spot checks.
10. A Smart First Step, Not the Final Word
FT-IR is a precision screening tool, not a replacement for structural or safety testing. By confirming chemical suitability first, it makes every subsequent test more targeted, more meaningful, and more cost-effective.
Where FT-IR Is Commonly Applied
FT-IR delivers strong results for any material with a defined chemical composition — particularly where materials look similar but perform very differently:
Table
Material Category
Why FT-IR Matters
Coatings & Anti-Corrosion Products
Verify formulation integrity before application
Construction Adhesives & Sealants
Confirm chemical type and detect substitution
Polymers, Rubber & Damping Components
Identify grade and detect degradation
Insulation, Foam & Plastics
Distinguish between visually similar materials
Know the Limits
FT-IR is a tool of precision — not a universal solution. It cannot replace structural load testing, crack detection, or engineering safety assessments. Those require dedicated mechanical and non-destructive testing methods. Used within its proper scope, however, FT-IR is one of the most efficient QC investments available.
Why ALS Testing
ALS Testing is an internationally accredited laboratory based in Thailand, delivering FT-IR analysis as part of a comprehensive, science-driven QC approach.
When materials enter the process already verified for chemical identity, condition, and conformance, the entire quality system performs better:
✅ Fewer surprises downstream
✅ More targeted advanced testing
✅ Stronger documentation for technical and commercial decisions
✅ Lower risk of costly late-stage failures
FT-IR with ALS Testing does not just check a box.
It changes the way organizations think about quality — from reactive to proactive, from assumption to evidence, from risk to confidence.
When first-line QC is right, everything that follows works better.

ICE vs. EV: A New Kind of Risk
The shift from combustion engines (ICE) to electric vehicles (EV) changes more than the power source — it changes the entire risk profile.
ICE systems fail through mechanical wear — predictable, repairable.
EV systems fail through electrical faults and thermal instability — sudden, dangerous, and potentially irreversible.
Even a few microns of contamination can trigger a battery short circuit, leading to thermal runaway — and potentially fire or explosion.
Why ISO 16232 Now Matters for Safety
The updated VDA 19.1 (3rd Edition, 2025), developed by 40+ leading automotive companies, elevates ISO 16232 from a quality standard to a functional safety requirement, introducing:
Particle analysis below 50 microns
SEM/EDX inspection techniques
Standardized dry extraction methods
Failure assessment for battery and electronic components
How Contamination Causes EV Failures
In high-voltage EV systems (400–800V), small conductive particles can cause:
Short circuits
Electrical arcing
Insulation breakdown
Leakage currents
These failures occur without warning — making cleanliness a safety-critical design requirement, not just a quality checkpoint.

Introduction
In the modern automotive industry, component precision and reliability are paramount — particularly with the growing adoption of intelligent braking systems, high-pressure fuel systems, and electric vehicles. One critical aspect often overlooked is technical cleanliness: the control of micron-level particles that can cause blockages, wear, and damage to critical systems, ultimately leading to costly product recalls.
Establishing a Cleanliness Lab aligned with Tier 1 Automotive standards is therefore not merely a compliance requirement — it is a strategic risk management initiative.
What is a Cleanliness Lab?
A Cleanliness Lab is a controlled laboratory facility designed to assess the cleanliness of automotive components through particle extraction and analysis, ensuring contamination levels remain within defined specifications.
For Tier 1 Suppliers, the lab functions as a quality gateway prior to OEM delivery — verifying product conformance, reducing rejection risk, and strengthening customer confidence. Applicable standards include ISO 16232 and VDA 19, both of which define systematic and reproducible testing methodologies. Organizations that meet these standards gain a competitive advantage within the global automotive supply chain.
Laboratory Infrastructure Requirements
Reliable test results depend on a well-designed facility. Key infrastructure elements include:
Cleanroom controlled to ISO Class 5–8
HEPA filtration system to minimize airborne particle levels
Positive pressure system to prevent external air ingress
Segregated zones for sample preparation, extraction, and analysis
One-way flow layout to minimize cross-contamination
Essential Equipment

Particle Extraction
Filtration
Analysis
Reporting
To ensure process reliability and integrity, the following must also be in place:
Clearly defined Standard Operating Procedures (SOPs)
Blank testing for quality control verification
Process validation
Traceability systems and data integrity controls
Personnel Competency
Despite advances in technology, personnel remain the most critical factor in Cleanliness Lab quality assurance. Required competencies include laboratory instrument operation, particle analysis techniques, and a working knowledge of ISO and VDA standards. Organizations must maintain continuous training, competency assessments, and periodic skill reviews.
Human factors also represent a significant contamination risk — including improper gowning, deviation from SOPs, and inappropriate behavior within the cleanroom — all of which can directly compromise test accuracy and overall system reliability.
Development Challenges
Building a Cleanliness Lab presents several challenges:
Capital investment for cleanroom construction and specialized equipment procurement
Standard complexity requiring expert knowledge for accurate interpretation and implementation
Upstream process control — an unstable manufacturing process limits the effectiveness of laboratory testing alone
Organizations are advised to develop both manufacturing controls and laboratory capabilities concurrently to achieve sustainable Tier 1 compliance.
Future Outlook: Smart Cleanliness Lab
The next generation of cleanliness laboratories is evolving toward intelligent, automated systems, incorporating:
AI-powered particle analysis
Automated microscopy
Real-time data connectivity
Integration with manufacturing execution and quality management systems enables end-to-end quality control, reducing cycle time, improving result consistency, and supporting compliance with increasingly stringent industry standards.
From Compliance to Competitive Advantage
A Cleanliness Lab is not merely a testing facility — it is an integral component of a holistic quality management system, spanning product design, manufacturing, and delivery. Organizations that establish a fully compliant Cleanliness Lab will be well-positioned to meet OEM requirements, reduce long-term operational risk, and sustain competitiveness in the global automotive market.
Investment in a Cleanliness Lab is an investment in long-term business sustainability.
FAQ
Is a Cleanliness Lab required for all manufacturing facilities? Not universally — however, it is essential for high-precision or safety-critical components, particularly in electric vehicle, electronics, and stringent-cleanliness applications.
How should an organization begin? Conduct a Gap Analysis against ISO 16232 and VDA 19, then develop a structured implementation plan covering facility design, equipment, and process requirements.
What is the estimated budget? Costs range from hundreds of thousands to several million baht, depending on lab scale, technology scope, and target compliance level.
How long does implementation take? Typically 3–12 months, subject to organizational readiness and system complexity.
What are common implementation mistakes? Inadequate facility design, unclear SOPs, insufficient personnel training, and failure to address upstream process control — resulting in test outcomes that do not reflect real-world conditions.

Anion/Cation Analysis · Ion Chromatography · GCMS · ICP-MS · RoHS/REACH Compliance · PCB Testing
ISO/IEC 17025 Accredited | Anion Test Specialist | Full Chemical Analytical Suite
The automotive industry’s shift toward electronics-intensive vehicle architectures, from advanced driver assistance systems (ADAS) to battery electric powertrains, has fundamentally changed the chemical testing requirements of automotive supply chains. Modern vehicles contain hundreds of electronic control units, kilometres of wiring, and sophisticated PCB assemblies whose reliability depends critically on chemical cleanliness, ionic contamination control, and compliance with global hazardous substance regulations.
At the same time, automotive chemical testing encompasses traditional analytical disciplines that remain essential: trace element analysis by ICP-MS, organic compound identification by GCMS, REACH and RoHS substance screening, and the growing discipline of ion chromatography for ionic contamination measurement, the ‘anion test’ that has become a critical quality control tool for automotive electronics manufacturers.
ALS Testing provides a comprehensive suite of chemical and electronics testing services, combining specialist ion chromatography capability with broad analytical chemistry capacity across ICP-MS, GCMS, FTIR, and regulatory compliance screening. With anion testing reaching search volumes of 210 per month in Malaysia – and no competitor currently offering well-developed content on this topic in the Malaysian market – ALS has a clear opportunity to establish content authority and capture this commercially significant keyword cluster.
Ion Chromatography – Anion & Cation Analysis
Ion chromatography (IC) is an analytical technique that separates and quantifies ionic species, both anions and cations, dissolved in an aqueous extract. In automotive and electronics testing, IC is applied to measure ionic contamination on component surfaces, in process fluids, and in assembly environments. The ‘anion test’ is shorthand for ion chromatography analysis of anionic species, has become one of the most widely applied quality control tests in automotive electronics manufacturing.
What Is Anion Testing?
Anion testing by ion chromatography quantifies the concentration of negatively charged ionic species, particularly chloride (Cl⁻), fluoride (F⁻), sulfate (SO₄²⁻), nitrate (NO₃⁻), phosphate (PO₄³⁻), and a range of organic acid anions including acetate, formate, and oxalate, in an aqueous extract of a component or material. These anions are of critical concern in automotive electronics because many of them are aggressive corrosion initiators and electrolytic conductors that can cause:
Electrochemical corrosion of metal conductors and contact surfaces
Dendritic growth (metallic whisker growth between PCB conductors under voltage bias)
Leakage current increase that triggers false signals in sensitive electronic circuits
Delamination of PCB laminates and conformal coatings in the presence of moisture
Accelerated corrosion of solder joints and connector contacts
In automotive applications, the primary source of ionic contamination is residual flux from PCB soldering processes, particularly when no-clean flux residues are not fully removed or when water-soluble flux residues are inadequately cleaned. Process water, fingerprints, environmental deposition, and chemical exposure during manufacturing are secondary sources.
Ion Chromatography Test Method – IPC-TM-650 2.3.28 / J-STD-001
The primary standard for ionic contamination testing of PCB assemblies is IPC-TM-650 Method 2.3.28, which defines the extraction method (a mixture of isopropyl alcohol and water applied to the PCB surface) and specifies the ion chromatography analysis for both anions and cations. The J-STD-001 standard (Requirements for Soldering Electrical and Electronic Assemblies) references cleanliness requirements that may require IC analysis for qualification.
ALS conducts ionic contamination testing by IC to IPC-TM-650 2.3.28, providing results in µg/cm² for each ionic species identified, against the limits specified by the client’s cleanliness specification or OEM requirement. Results identify both the type and quantity of each ionic species, enabling manufacturers to verify compliance and infer potential root causes (such as chloride excess suggesting flux residue or organic acids suggesting flux decomposition products).
Cation Analysis – Sodium, Potassium, Ammonium & Others
In addition to anion analysis, ALS provides cation analysis by IC for the principal positively charged ionic species of concern in electronics: sodium (Na⁺), potassium (K⁺), ammonium (NH₄⁺), and the amines associated with no-clean flux formulations (particularly methylamine and triethanolamine, which are characteristic of amine-based flux activators). Elevated ammonium or amine concentrations can indicate inadequate removal of flux activator residues, which in combination with humidity can cause under-board corrosion and leakage current failures.
RoHS & REACH Compliance Testing
The Restriction of Hazardous Substances (RoHS) Directive and the Registration, Evaluation, Authorisation and Restriction of Chemicals (REACH) Regulation are the two most significant global regulatory frameworks governing chemical content in electrical and electronic products. Compliance with both is mandatory for automotive electronics products supplied to the EU market, and is increasingly required by global OEMs as a contractual supply chain requirement regardless of the target market.
RoHS Compliance Screening – IEC 62321 Series
The RoHS Directive restricts the use of six hazardous substances in electrical and electronic equipment: lead (Pb), mercury (Hg), cadmium (Cd), hexavalent chromium (Cr(VI)), polybrominated biphenyls (PBB), and polybrominated diphenyl ethers (PBDE). RoHS 2 (Directive 2011/65/EU and its amendments) added four phthalates (DEHP, BBP, DBP, and DIBP), making ten restricted substances in total.
ALS provides RoHS compliance screening to the IEC 62321 series of test methods, which defines the analytical methods for determination of each restricted substance group. Screening begins with X-ray fluorescence (XRF) screening for elemental species (Pb, Hg, Cd, Cr) and proceeds to confirmatory quantitative analysis by ICP-MS or ICP-OES where XRF screening indicates potential exceedance. Hexavalent chromium is determined specifically by UV-Vis spectrophotometry, and phthalates are determined by GCMS.
REACH – SVHC Screening
The REACH regulation requires declaration of substances of very high concern (SVHC) in articles above a concentration threshold of 0.1% w/w, when the SVHC concentration exceeds 0.1% in the article as a whole. The SVHC candidate list, published by the European Chemicals Agency (ECHA) and updated regularly, now contains over 230 substances, including phthalates, heavy metals, aromatic amines, certain polymers, and flame retardants. ALS provides targeted SVHC screening for the substances most commonly encountered in automotive materials and electronic components, using appropriate analytical methods including XRF, ICP-MS, GCMS, and IC.
GCMS – Organic Chemical Analysis
Gas chromatography-mass spectrometry (GCMS) is the primary analytical tool for identification and quantification of organic compounds, including solvents, plasticisers, flame retardants, process chemicals, and contaminants in automotive materials and components. In automotive chemical testing, GCMS is applied across a range of programmes.
GCMS Applications in Automotive Testing
VOC and SVOC emissions analysis: GCMS is the detection method used in thermal desorption analysis to VDA 278 and ISO 12219, providing a detailed compound-by-compound profile of organic emissions from interior materials. Contaminant identification: when unknown organic contaminants are found on component surfaces, in lubricants, or in process fluids, GCMS compound identification provides the molecular-level identification needed for source investigation and corrective action. Phthalate analysis for RoHS compliance: GCMS is the confirmatory method for determination of phthalates (DEHP, BBP, DBP, DIBP) in materials screened initially by XRF. Solvent and process chemical residue analysis: GCMS identifies residual solvents and cleaning agents on component surfaces after cleaning processes, providing evidence of adequate cleaning or contamination by inappropriate process chemicals.
ICP-MS & ICP-OES – Trace Element Analysis
Inductively coupled plasma mass spectrometry (ICP-MS) and inductively coupled plasma optical emission spectrometry (ICP-OES) are the premier techniques for trace and ultra-trace elemental analysis in automotive materials, process fluids, and environmental samples. These techniques provide multi-element analysis at concentrations from percentage levels (ICP-OES) down to parts per trillion (ICP-MS) in dissolved samples, making them essential tools for restricted element screening, material composition verification, and contamination source tracing.
Trace Element Analysis Applications
RoHS element screening: ICP-MS and ICP-OES provide confirmatory quantitative analysis for lead, mercury, cadmium, and total chromium in materials where XRF screening has indicated potential RoHS exceedance. Automotive fluid analysis: engine oils, coolants, hydraulic fluids, and gear lubricants are analysed by ICP-OES for wear metals (iron, copper, aluminium, chromium), additive elements (zinc, phosphorus, molybdenum), and contaminant elements as part of condition monitoring and failure investigation programmes. Material composition verification: ICP analysis confirms the elemental composition of alloys, platings, and surface treatments against specified composition limits. Environmental sample analysis: ALS applies ICP-MS to environmental water and soil samples in support of automotive manufacturing facility environmental monitoring and regulatory compliance programmes.
PCB & Electronics Component Testing
Automotive electronics components, including PCBs, connectors, sensors, power modules, and wire harness assemblies, are subject to some of the most demanding chemical cleanliness and material compliance requirements in the electronics industry. The consequences of chemical contamination in automotive safety systems, powertrain controls, or battery management electronics are severe, ranging from intermittent operation through to complete functional failure in safety-critical systems.
PCB Ionic Contamination Testing
Ion chromatography analysis of PCB ionic contamination (IPC-TM-650 2.3.28) is described in detail in the Ion Chromatography section above. ALS provides this as a standard service for automotive PCB manufacturers and assemblers, supporting both production quality control and OEM qualification requirements.
Solderability Testing
Solderability testing evaluates the wettability of component leads, PCB pads, and solder surfaces, specifically the ability of liquid solder to spread uniformly across a surface. Poor solderability leads to cold solder joints, dewetting, and non-wet opens, which are a significant source of early-life failures in automotive electronics. ALS provides solderability testing by wetting balance (J-STD-002) and dip-and-look methods (IPC-TM-650 2.4.12) to support incoming component qualification and process control.
Conformal Coating Inspection & Analysis
Conformal coatings applied to automotive PCBs provide protection against moisture, contamination, and mechanical stress. ALS provides analysis of conformal coating composition by FTIR to verify coating type, cross-section analysis by optical and scanning electron microscopy to assess coating thickness and uniformity, and adhesion testing to evaluate bonding integrity of the coating to the PCB surface. These tests support both coating process validation and investigation of coating failures in field-returned assemblies.

Frequently Asked Questions – Chemical & Electronics Testing
Q: What is an anion test and why is it important for PCB manufacturing?
An anion test is ion chromatography (IC) analysis of ionic contamination on a PCB or electronic component surface, specifically targeting negatively charged ionic species including chloride, fluoride, sulfate, nitrate, phosphate, and organic acid anions. These anions are important in PCB manufacturing because they are the primary ionic contaminants that cause electrochemical corrosion, dendritic growth, and leakage current failures in PCB assemblies, particularly in humid environments. The anion test is conducted to IPC-TM-650 Method 2.3.28 and provides results in µg/cm², comparable to OEM or IPC cleanliness acceptance limits.
Q: What is the difference between RoHS and REACH, and does ALS test for both?
RoHS (Restriction of Hazardous Substances Directive) restricts the use of ten specific hazardous substances in electrical and electronic equipment placed on the EU market: six original substances (lead, mercury, cadmium, hexavalent chromium, PBB, PBDE) plus four phthalates added by RoHS 2. REACH is a broader chemical regulation requiring identification and communication of substances of very high concern (SVHC) in articles. The SVHC candidate list contains over 230 substances. ALS provides compliance screening for both RoHS and REACH, using appropriate analytical methods for each substance category. We can provide a combined RoHS and REACH SVHC screening programme from a single sample submission.
Q: Can ALS identify unknown contaminants on automotive components?
Yes. Unknown contaminant identification is one of our most commonly requested analytical services. Our approach typically begins with FTIR analysis to identify organic contaminants and provide a rapid initial classification. SEM-EDX is applied to characterise the morphology and elemental composition of inorganic contaminants or particles. GCMS provides definitive molecular identification of organic species when FTIR yields an ambiguous or incomplete result. ICP-MS can quantify trace elements in dissolved contaminants. By applying this suite of techniques in sequence, ALS can identify the chemical nature and likely source of most contaminants encountered in automotive manufacturing environments.
Q: How do I interpret ion chromatography results for my PCB cleanliness specification?
IC results for PCB ionic contamination are typically expressed as µg/cm² of each ionic species, calculated from the total extracted mass divided by the board surface area analysed. These results are compared against the cleanliness acceptance limit specified by your OEM, your customer’s specification, or a standard such as IPC-7711. Common acceptance limits range from 0.2 µg/cm² to 1.56 µg/cm² for total ionic contamination, depending on the application’s criticality. Our report will state the measured concentration of each ionic species and compare it against your specified limit to provide a clear technical conclusion regarding compliance. If you need guidance on interpreting results or selecting appropriate cleanliness limits for your application, our technical team is available to advise.
Q: Does ALS provide GCMS analysis for VOC testing as well as RoHS phthalate screening?
Yes. Our GCMS capability covers both applications and more. For VOC/FOG emissions analysis, GCMS is the detection method used in thermal desorption analysis to VDA 278, providing compound identification and quantification of organic emissions from automotive interior materials. For RoHS phthalate screening, GCMS is the confirmatory analytical method applied after XRF screening for samples that require quantitative phthalate determination. Additionally, GCMS is applied to unknown contaminant identification, solvent residue analysis, process chemical characterisation, and environmental sample analysis. Our GCMS systems operate in full-scan mode for compound identification and selected ion monitoring (SIM) mode for trace-level quantification.

What Is Automotive Testing?
Automotive testing is the systematic evaluation of materials, components, sub-assemblies, and complete vehicle systems to verify that they meet defined performance, safety, chemical, and regulatory specifications. It spans the entire manufacturing lifecycle, from raw material qualification through prototype validation, production quality control, and field failure investigation.
In scope, automotive testing covers a broad spectrum of disciplines: physical and mechanical testing of materials and structures; chemical analysis of coatings, fluids, and polymer compounds; cleanliness and contamination analysis of precision components and hydraulic systems; failure analysis of components returned from field or production; and environmental simulation testing to assess durability under real-world conditions including temperature cycling, humidity, corrosion, and vibration.
Testing can be classified in several ways. Destructive testing involves irreversible analysis (cross-sections, chemical extraction, or mechanical fracture testing) and yields the most detailed information about a component’s internal structure and material composition. Non-destructive testing (NDT) allows a component to be evaluated and returned to service, using techniques such as SEM imaging, X-ray inspection, or particle extraction. Testing can also be categorised by regulatory purpose: type approval testing confirms conformance to legal and OEM requirements for production intent components, while R&D testing supports early-stage development, material selection, and process optimisation.
Why Independent Automotive Testing Matters
Independent, third-party laboratory testing plays a central role in modern automotive manufacturing for three critical reasons.
First, regulatory and OEM acceptance: the vast majority of global OEMs require testing results from ISO/IEC 17025 accredited independent laboratories. In-house test reports, regardless of the sophistication of the equipment, are typically not accepted as compliance evidence for OEM approval processes, type approvals, or regulatory submissions. Accredited laboratory results carry a level of traceability and methodological rigour that in-house testing cannot formally provide.
Second, liability protection: when a component or material is tested by an independent laboratory, the test report provides documented, objective evidence of compliance at the time of manufacture. This evidence is critical in the event of warranty claims, product liability disputes, or regulatory investigations. An independent report reduces risk exposure for suppliers and protects against unjustified claims.
Third, objectivity and confidence: there is no conflict of interest in third-party testing. ALS operates independently of its clients and has no stake in any particular test outcome. Our results reflect reality, which is exactly what manufacturers, regulators, and end customers require.
ALS provides all of the above, with 40+ years of global expertise and a local team who understands the nuances of the Malaysian and Southeast Asian automotive supply chain.
Automotive Testing vs In-House Testing: Key Differences
The question of whether to conduct testing in-house or to outsource to a contract testing laboratory is one that many automotive suppliers face, particularly as they scale up production volumes or seek new OEM approvals. The decision involves multiple dimensions beyond simple cost comparison.

ISO/IEC 17025 Accredited | Full Environmental Simulation Suite | OEM Standard Testing
The materials that make up a modern automobile are subjected to conditions that most materials would never encounter: temperature extremes from −40°C to +120°C and beyond; salt-laden road spray that attacks every exposed metal surface; UV radiation that degrades polymers and fades pigments; humid tropical heat that accelerates corrosion and swells seals; and the constant off-gassing requirements of interior materials that affect the air quality cabin occupants breathe every day.
Automotive materials testing, which encompasses VOC emissions analysis, corrosion testing, environmental simulation, thermal characterisation, and chemical content analysis, validates that materials and components survive these conditions and meet the specifications that OEMs and regulations define. With combined search volumes exceeding 430 searches per month in Malaysia for VOC and salt spray testing alone, this is one of the most commercially active testing categories in the regional automotive market.
ALS Testing is accredited to ISO/IEC 17025:2017 and offers a comprehensive range of automotive materials and environmental testing services, covering the key standards that govern material qualification for Malaysian and global automotive supply chains. Critically, ALS currently has no content covering VOC testing – the highest-volume keyword in our portfolio – making this Pillar Page a priority content investment.
VOC Emissions Testing for Automotive Interior Materials
Volatile organic compound (VOC) emissions from automotive interior materials are a significant concern for both regulatory compliance and consumer experience. Interior materials including instrument panels, headliners, seat foams, carpets, door trim panels, adhesives, and sealants all contribute to the volatile chemical environment inside the vehicle cabin. Elevated VOC concentrations in new vehicles have been associated with health concerns, including irritation, headache, and in extreme cases, sensitisation, and are subject to increasingly stringent OEM specifications and, in some markets, regulatory limits.
Automotive VOC testing is governed by several key standards that specify the test method, temperature conditions, sampling duration, and analytical approach. ALS provides testing to the primary automotive VOC standards required by global OEMs.
VDA 278 – Thermal Desorption Analysis of Automotive Interior Materials
VDA 278 is the German automotive industry standard for analysis of organic emissions from automotive interior components using thermal desorption GC-MS. The standard defines two heating stages: 90°C for VOC determination (volatile organic compounds) and 120°C for FOG determination (semi-volatile high-boiling condensable compounds, applied to a small sample of the material under controlled conditions. The emitted compounds are collected on a Tenax sorbent tube, thermally desorbed, and analysed by gas chromatography-mass spectrometry (GC-MS) to provide a quantitative profile of organic emissions.
VDA 278 is required by German OEMs (BMW, Volkswagen Group, Mercedes-Benz, Audi) and their Tier-1 suppliers, and is widely adopted across the global automotive supply chain. It provides quantitative data for comparison against specified emission limits for individual compounds and compound groups, typically expressed in µg/g of material.
ISO 12219 – Interior Air of Road Vehicles
ISO 12219 is the international standard series covering the measurement of VOC concentrations in vehicle interiors. The standard defines test methods for measuring VOC concentrations in the cabin air of complete vehicles (ISO 12219-1, bag method) and for emissions from individual interior components (ISO 12219-2 to ISO 12219-7, covering various chamber and micro-chamber methods). ALS provides component-level VOC testing to the ISO 12219 chamber methods, enabling material qualification against OEM VOC specifications defined under this standard.
VDA 275 – Formaldehyde Emission Testing
Formaldehyde is a specific VOC of regulatory and health concern, subject to dedicated test methods and specific emission limits in many OEM specifications. VDA 275 specifies a bottle method for determination of formaldehyde emissions from automotive interior non-metallic materials, using photometric analysis of the extracted formaldehyde. ALS provides formaldehyde testing to VDA 275 as part of our VOC testing capability, enabling clients to meet the specific formaldehyde limits defined by German and other OEMs.
ISO 6452 – Fogging Testing
Fogging testing determines the propensity of automotive interior materials to produce condensable vapours that deposit on the vehicle windscreen as a visible fog film. This is both an aesthetic issue (the fog film impairs driver visibility) and an indicator of high-boiling organic emissions from interior materials. ISO 6452 defines both photometric (reflectance-based) and gravimetric (mass deposition) methods for fogging assessment. ALS provides fogging testing to ISO 6452 as part of our interior emissions testing portfolio.
Corrosion & Salt Spray Testing
Corrosion is one of the most persistent and economically significant degradation mechanisms in automotive components and structures. Road salt, humid climates, and the electrochemical environment created by dissimilar metals in contact create conditions that attack metal surfaces, coatings, and plated surfaces continuously throughout a vehicle’s service life. Corrosion testing replicates these conditions in accelerated form, enabling assessment of coating quality, material selection, and corrosion protection effectiveness in a fraction of the real-world timescale.
ISO 9227 – Neutral Salt Spray Testing (NSS)
ISO 9227 is the primary international standard for salt spray (salt fog) corrosion testing, covering three test atmospheres: neutral salt spray (NSS), acetic acid salt spray (AASS), and copper-accelerated acetic acid salt spray (CASS). In the NSS test, the most widely applied, specimens are exposed to a continuously atomised 5% sodium chloride solution at 35°C for defined durations, typically ranging from 96 hours to 1,000 hours or more depending on the OEM specification. The standard defines the test apparatus requirements, solution chemistry, temperature tolerances, and evaluation criteria for assessing corrosion protection performance.
ALS salt spray testing to ISO 9227 is applied to painted and coated metal components, fasteners and fixings, electroplated surfaces, and automotive exterior and underbody components. Results are documented through visual examination of corrosion creep from scribe lines, blister formation, and spot corrosion. The resulting data is then classified according to ISO 10289, allowing manufacturers to verify compliance with their specific OEM requirements.
ASTM B117 – Standard Practice for Operating Salt Spray Apparatus
ASTM B117 is the American equivalent of ISO 9227 for neutral salt spray testing, widely required by American OEMs and their supply chains. The test conditions under ASTM B117 are equivalent to ISO 9227 NSS, with 5% sodium chloride solution at 35°C, but the evaluation criteria and acceptance requirements may differ between specifications. ALS can conduct salt spray testing to ASTM B117 for clients whose OEM specifications reference this standard.
Cyclic Corrosion Testing
While continuous salt spray testing (ISO 9227, ASTM B117) provides a standardised accelerated corrosion environment, cyclic corrosion testing, which alternates between salt spray exposure, humidity, ambient drying, and optional UV exposure phases, which many OEMs consider more representative of real-world corrosion progression. ALS offers cyclic corrosion testing to selected OEM and industry standards, providing a more nuanced assessment of corrosion protection performance for clients whose OEM specifications require this approach.
Thermal & Environmental Simulation Testing
Automotive components experience extreme thermal and environmental conditions during manufacture, assembly, shipping, and service. Environmental simulation testing replicates these conditions in controlled laboratory settings, enabling assessment of component integrity, material stability, and functional performance across the full environmental envelope.
Thermal Shock Testing (IEC 60068-2-14)
Thermal shock testing exposes components to rapid transitions between high and low temperature extremes, replicating the shock experienced by components during engine start-stop cycles, cold weather startup, or transition between heated and cooled environments. IEC 60068-2-14 specifies the thermal shock test method, defining the temperature extremes, transition time, dwell time at each extreme, and number of cycles. Thermal shock testing is applied to automotive electronics, sensors, connectors, and any component where thermal cycling could cause fatigue cracking, delamination, or seal failure.
Thermal Cycling & Temperature Endurance Testing (IEC 60068-2-1 / 2-2)
Thermal cycling testing exposes components to repeated temperature cycles between defined minimum and maximum temperatures, with controlled ramp rates and dwell times. Unlike thermal shock, cycling involves slower temperature transitions that stress materials through differential thermal expansion rather than rapid temperature shock. IEC 60068-2-1 covers cold testing and IEC 60068-2-2 covers dry heat testing. These methods are applied to automotive materials, electronics, and polymer components to assess stability and endurance across the operational temperature range.
Humidity & Damp Heat Testing (IEC 60068-2-78)
Humidity testing exposes components to elevated temperature and relative humidity conditions, assessing resistance to moisture ingress, hydrolytic degradation, corrosion, and swelling. IEC 60068-2-78 specifies the damp heat steady-state test at 40°C and 93% RH, widely applied to automotive electronics and connector systems. ALS humidity testing supports qualification of automotive electronics for tropical and humid climate markets including Southeast Asia, where humidity resistance is a particularly critical performance requirement.

Frequently Asked Questions – Materials & Environmental Testing
Q: What is VDA 278 and which OEMs require it?
VDA 278 is the German automotive industry standard for measuring organic emissions from non-metallic interior materials using thermal desorption gas chromatography-mass spectrometry. It is required by German OEMs including BMW, Volkswagen Group (Volkswagen, Audi, SEAT, SKODA, Porsche), Mercedes-Benz, and their direct suppliers. The standard provides both VOC and FOG (semi-volatile) results, expressed in µg/g of material, enabling material qualification through comparison against OEM-specified emission limits for individual compounds and compound groups.
Q: What is the difference between salt spray testing to ISO 9227 and ASTM B117?
ISO 9227 and ASTM B117 specify equivalent test conditions for neutral salt spray testing, both using 5% sodium chloride solution at 35°C, but they originate from different standards organisations (ISO vs ASTM) and may have different specification requirements in terms of evaluation methods and acceptance criteria. ISO 9227 is the standard required by most European and Asian OEM specifications, while ASTM B117 is required by American OEM specifications. ALS can test to either standard based on your OEM specification requirement.
Q: How long does a salt spray test take?
The duration of a salt spray test is defined by the OEM specification or the standard being tested to, and can range from 96 hours (4 days) for some coating qualification tests to 240, 500, or 1,000 hours for more demanding corrosion resistance requirements. Long-duration tests require advance planning and scheduling. Please contact our team early in your project timeline to allow for test scheduling, and to confirm whether interim inspection requirements are specified.
Q: Can ALS test for both VOC emissions and formaldehyde from the same material sample?
Yes. It is common for OEM specifications to require both general VOC/FOG analysis (by VDA 278) and specific formaldehyde determination (by VDA 275) from the same material. ALS can conduct both tests from a single sample submission, minimising the material required and simplifying the sample preparation and submission process. Please specify both test requirements when making your enquiry.
